Robert Haas	890194f14d	Comment fixes related to logical decoding. ... Andres Freund, per complaints by Peter Eisentraut.	12 years ago
Tom Lane	ea177a3ba7	Remove unportable use of anonymous unions from reorderbuffer.h. ... In b89e151054 I had assumed it was ok to use anonymous unions as struct members, but while a longstanding extension in many compilers, it's only been standardized in C11. To fix, remove one of the anonymous unions which tried to hide some implementation specific enum values and give the other a name. The latter unfortunately requires changes in output plugins, but since the feature has only been added a few days ago... Andres Freund	12 years ago
Robert Haas	97e899e1b8	Fix test_decoding regression test outputs. ... Commit 6f37c08057 removed whitespace from the SQL file but not the expected-output file, and commit 7e8db2dc42 changed the error message without updating the expected outputs.	12 years ago

Robert Haas	b89e151054	Introduce logical decoding. ... This feature, building on previous commits, allows the write-ahead log stream to be decoded into a series of logical changes; that is, inserts, updates, and deletes and the transactions which contain them. It is capable of handling decoding even across changes to the schema of the effected tables. The output format is controlled by a so-called "output plugin"; an example is included. To make use of this in a real replication system, the output plugin will need to be modified to produce output in the format appropriate to that system, and to perform filtering. Currently, information can be extracted from the logical decoding system only via SQL; future commits will add the ability to stream changes via walsender.
